摘　　要：因城际铁路穿越城市之间,前期规划设计出现缺陷在所难免,会因政策问题、设计变更等因素造成工期延误。为解决此类问题,本文以杭临城际铁路工程为背景,针对城际铁路高架桥现浇连续箱梁与相邻现浇简支梁优化张拉端实现同时施工所采取的措施进行了详细的介绍,对优化方案及相关施工工艺进行探讨,通过优化张拉端设计以增加工作面,多作业面同时施工,从而加快了施工进度,满足原合同工期,最终实现工期目标。Due to the intercity railway crossing between cities,defects in the preliminary planning and design are inevitable,and the construction period will be delayed due to policy problems,design changes and other factors.In order to solve such problems,this paper takes the Hangzhou-Lin’an intercity railway line project as the background,in view of the inter-city railway viaduct cast-in-situ continuous box girder with adjacent cast-in-situ beam optimization tensioning end implementation construction measures taken at the same time has carried on the detailed introduction,discusses optimization scheme and related construction technology,through optimizing tensioning end design to increase the working face,multiple working face construction at the same time,thus speed up the construction progress,meet the original contract time limit,and finally achieve the time limit target.
